Referring now to the drawn Kndetaih l In a circuit closer, a baseboard a, semia baseboard t ;ed at any circular strip secured to said baseboard and suitable material tleoured it, h obomd graduated to indicate degrees of tempera-- is a semicircular r'rip p .1 1 i 'ture, a rod secured to said baseboard con- 45 marked to indicate the various degrees or centrically of said strip and offset from said temperature. Suitably fastened to the base baseboard, cellars adjustahly mounted upon 3. and oiiset outwardly therefrom a said rod, fingers carried by said collars and mental rod disposed concentrically oi? the overlying; said strip and adapted to register strip 2 and having the Jreinities with predetermined marks on said strip, a 59 thereof fastened to the lease. Project shatjt't rotatably mounted at the center of the outwardly from the base l at the center oi are described by said strip, a finger fixed to the arm described by the strip 2 is shaft l; said shaft and movable over said strip and and secured to the shaft 1} is an indicator adapted to engage said first-1nentioned finger 5 movable over the graduated surface fingers, the terminals of an alarm circuit of the strip 2.. Fixednpon the shaft is a secured to said last-mentioned finger and pinion 6 with which meshes the teeth a rod respectively whereby the alarni in the 2 Lear/534 circuit willbe sounded when the last-mentioned finger engages either of the firstmentioned fingers, a pinion on said shaft, a nit-k meshing with said pinion, a lever 5 pivoted between its ends and having" one extremity connected to said rack, a bracket adjacent to the remaining extremityof said lever, a thermostat carried by said bracket and connected to said lever, and a swing connected to said im'ei' and eounterzmting 10 said tha 'u'mstat.
